Question about dependencies in conda.recipe/meta.yaml

[martinholmer]

@hdoupe and @andersonfrailey, I don't understand the following Tax-Brain requirements specification:

requirements:
  build:
    - python
    - "taxcalc>1.0.0"
    - "behresp>=0.6.0"
    - "pandas>=0.23"
    - dask
    - "numpy>=1.13"

  run:
    - python
    - "taxcalc>1.0.0"
    - "behresp>=0.6.0"
    - "pandas>=0.23"
    - dask
    - "numpy>=1.13"

Can't you drop out the pandas and numpy lines from both sets of dependencies? It would seem that they are redundant (and could cause dependency conflicts in the future) because taxcalc already lists pandas and numpy as requirements. Certainly, the behresp packages, which make use of both numpy and pandas, are made just fine with using this pared-down set of requirements:

requirements:
  build:
    - python
    - "taxcalc>=1.0"

  run:
    - python
    - "taxcalc>=1.0"

@martinholmer, you're right. I've dropped the pandas and numpy requirements in PR #18.

OK. Good.
